f(x) = 3x +4f(x) = 5x +2f(x) = -4x +11f(x) = -4x +11 (same table as problem 3)Step-by-step explanation:
To write the equation for f(x) in slope-intercept form, you need to know the slope and the y-intercept. The y-intercept is the value of f(x) when x=0. You can read this directly from the table.
The slope is the ratio of the change in f(x) to the change in x. It can be computed using the formula ...
m = (y2 -y2)/(x2 -x1)
where (x1, y1) and (x2, y2) are any two pairs of numbers from the table. You can use the first two table rows, for example.
__
1. m = (10 -4)/(3 -0) = 6/3 = 2; y-intercept = 4 (from ordered pair (0, 4))
y = mx +b . . . . line with slope m and y-intercept b
f(x) = 2x +4
__
2. m = (2 -(-3))/(0 -(-1)) = 5/1 = 5
f(x) = 5x +2
__
3. m = (11 -19)/(0 -(-2)) = -8/2 = -4
f(x) = -4x +11

The sum of first four terms is a G.P. is 30 and that of the last four terms is 960. if its first term is 2 find the common ratio .
Answers
If the sum of first four terms in a G.P. is 30 and that of the last four terms is 960, then the sum of the first 8 terms is 990
We also know that a = 2
sum of first 4 terms
= 2(r^4 - 1)(r-1) = 30
r^4 - 1 = 15r - 15
r^4 - 15r + 14 = 0
r = 1 works for the equation , but r = 1 would make all the terms of the
GP the same, so clearly not a solution
r^4 - 15r + 14 = 0 , a bit of trial and error ....
(r-1)(r - 2)(r^2 + 3r + 7) = 0
so r = 2 or r = not real
check: sum(4) = 2(2^4 - 1)/(2-1) = 30 , as needed
so r = 2 , BUT it does not work for sum(8)
sum(8) = 2(2^8 - 1)(2-1) = 510 , not 990 as necessary according to your second part of the question.
check your question.

Step-by-step explanation:
All the corresponding angles are marked congruent. If one corresponding side is marked congruent, you can claim AAS or ASA congruence for the triangles: one side and two angles. Of these, AAS is among the answer choices.
You must use AAS to show triangle congruence before claiming FH ≅ HK by CPCTC.

Answers
y = -2x - 4
--> Swap sides so that all variable terms are on the left hand side
-2x - 4 = y
--> Add 4 to both sides
-2x = y + 4
--> Divide both sides by -2
-2x/-2 = y+4/-2
--> Dividing by -2 undoes the multiplication by -2.
x = y+4/-2
--> Divide y+4 by -2
x = -y /2 -2
-------------------------------------------------------------
y = 1/4x + 5
--> Swap sides so that all variable terms are on the left hand side.
1/4x + 5 = y
--> Subtract 5 from both sides.
1/4x = y - 5
--> Multiply both sides by 4.
1/4x 1/4 = y - 5/ 1/4
--> Dividing by 1/4 undoes the multiplication by 1/4.
x = y - 5/ 1/4
--> Divide y - 5 by 1/4 by multiplying y - 5 by the reciprocal of 1/4.
x = 4y - 20

Answers
a. y = 5x + 80 = 5*4 + 80 = 20 + 80 = 100
b. a = 3-5c = 3 - 5*(-0.5) = 3 - (-2.5) = 3 + 2.5 + 5.5
c. n = 2d² - 5 = 2*(-2)² - 5 = 2* 4 - 5 = 8 - 5 = 3
